Philadelphia Trolley Tracks

Philadelphia Trolley Tracks is
a collection of photos, maps, and rosters showing Philadelphia's extensive
streetcar system as it was in the 20th century, and what remains today.
Traditional streetcar lines have lately enjoyed a resurgence, with new construction
and plans being laid in no less than 40 cities across the United States,
from Portland Oregon to Augusta Georgia. Only a handful of North American
cities held onto their streetcar lines; San Francisco and Toronto are expanding
theirs. Despite a bus-oriented transit authority, parts of Philadelphia's
trolley system survive.
